摘要：
面向轻度认知障碍患者家庭使用的定位系统应满足特定要求。系统应为用户提供亚米级精度，以便分析患者的运动轨迹，并具备良好的能效，使设备无需频繁充电。通过将高精度UWB与高能效蓝牙低功耗（BLE）技术相结合的混合定位系统，可以满足这些要求。本文提出了这样一种解决方案并进行了实验验证。在所提出的系统中，用户位置通过基于BLE的指纹定位方法获得。算法所使用的无线电地图在系统运行期间借助UWB子系统的支持自动创建。这种方法使用户能够尽可能频繁地重复系统校准，从而提高系统对环境变化的鲁棒性。
英文摘要：
Localization systems intended for home use by people with mild cognitive impairment should comply with specific requirements. They should provide the users with sub-meter accuracy allowing for analyzing patient's movement trajectory and be energy effective, so the devices do not need frequent charging. Such requirements could be satisfied by employing a hybrid positioning system combining accurate UWB with energy efficient Bluetooth Low Energy (BLE) technology. In the paper, such a solution is presented and experimentally verified. In the proposed system, user's location is derived using BLE based fingerprinting. A radio map utilized by the algorithm is created automatically during system operation with the support of UWB subsystem. Such an approach allows the users to repeat system calibration as often as possible, which raises systems resistance to environmental changes.
